I can't really answer (but I looked at the thread due to general interest). I bet others here will be able to though, but maybe a bit more info.
1) Says V8.... so is it a gas 5.4? The diesel is a V-8 too though maybe? (Answered my own question by finding the ad: It's gas, so I presume the 5.4)
2) What is the interior like? Converted? More bare? Is it a base you would build on or would you be tearing down to "cargo" anyway? Or do you want one just like how this one is (no windows, etc.)
3) Where has it lived? (Salt/rust, is that why the rockers are black or is that for other reasons? Looks like Cali plates now but if it's lived anywhere else that might be a factor.)
I can commiserate. I hate it when I know what I want, have the money to hand, and then CAN'T FIND ONE!
PS: One slightly odd thing that may just be an innocent mistake: Ad title says 2002 van whereas the informational sidebar says it's a 2001.
